The agar dilution method has been standardized by the CLSI for the susceptibility testing of Campylobacter species, and according to these standards, the disk diffusion method should be used only in screening for macrolide and ciprofloxacin resistance. Nevertheless, the disk diffusion test is currently widely used, since it is easy to perform in clinical microbiology laboratories. In this study...

21 The agar dilution method has been standardized by the CLSI for the susceptibility testing of 22 Campylobacter species, and according to these standards, the disk diffusion method should only 23 be used for the screening of macrolide and ciprofloxacin resistance. Nevertheless, the disk 24 diffusion test is currently widely used, since it is easy to perform in clinical microbiology 25 laborato...

BACKGROUND Staphylococcus saprophyticus is the second most frequent community-acquired causative agent of urinary tract infection (UTI). The objective of this study was to evaluate the susceptibility profile and resistance detection in Staphylococcus species. isolated from patients with UTI. MATERIALS AND METHODS The isolates were investigated using the disk diffusion method, Vitek I system, ...

Early availability of antifungal susceptibilities can ensure timely institution of targeted therapy in candidemia, which can improve patient outcomes. This study prospectively determines the agreement between the results of direct testing of antifungal susceptibilities from blood culture bottles by disk diffusion and Etest and the results of standardized susceptibility testing methods; direct t...

 Methicillin resistant Staphylococcus aureus (MRSA) has been emerged as a nosocomial and community acquired pathogen worldwide. There are many challenges for laboratory detection of MRSA. The aim of this study was to compare different phenotypic methods with PCR based method as a gold standard for detection of mecA gene to detection of MRSA. A total of 220 clinical isolates of S. aureus which w...

This study was conducted in order to compare the accuracy of detection of oxacillin-resistant staphylococci, defined by microdilution MICs, population analyses, and mec gene hybridization, with the Vitek GPS-SA Susceptibility Card with that of the standard inoculum (10(7) CFU) and high-inoculum (10(9) CFU) disk diffusion tests. By the standard inoculum disk diffusion test, 10 of 67 (15%) isolat...

Background and Aim:  Streptococcus sanguinis (S. sanguinis) is one of the effective bacteria in the formation of caries and periodontal diseases which are caused by dental plaque. Currently, the use of natural honey (NH) is considered as a method of reducing S. sanguinis and S. mutans in saliva, which results in reducing the dental plaque. The purpose of this study was to evaluate the effects o...

In this study, disk diffusion testing with ceftizoxime and cefuroxime was evaluated for use in predicting the susceptibility of Streptococcus pneumoniae to ceftriaxone and cefotaxime. Of the 194 isolates included in this study, 138 were susceptible, 34 were intermediate, and 22 were resistant to cefotaxime by MIC testing; 138 isolates were susceptible, 35 were intermediate, and 21 were resistan...

Based on the disscusion of the applicability of local approximation, the local stability of accretion disks with advection is studied together with the considerations of radial viscous force and thermal diffusion. For a geometrically thin, radiative cooling dominated disk, the thermal diffusion has nearly no effects on the thermal and viscous modes, which are both stable if the disk is also opt...

Two hundred and fifty tracheal aspirates were subjected to direct antimicrobial susceptibility testing by disk diffusion, Etest and inoculation on antibiotic-enriched MacConkey agar plates. Results were compared with those obtained using an automated system on microorganisms recovered from standard quantitative culture. A total of 255 microorganisms were isolated from 194 positive samples by th...
